I have a USB drive with NTFS partition leftover from Windows installation DVD. Tuxboot ran on the drive without any errors, but was unable to make it bootable. Instead the Windows installer's boot program was run. I tried formatting the drive (to NTFS) and reran Tuxboot, but the problem persisted. Reformatting to FAT32 solved the problem.
If NTFS is not supported at all, it would be nice to get an error message about this when an NTFS drive is selected.
Version: tuxboot-0.3.exe (Windows)
